Within the world of scooter tuning today there is a big selection of tuning parts available. This may leave you a little stuck when trying to choose the correct parts that actually make your scooter more useable. So we've put a few suggestions together to help you get the best reliable everyday road performance from a 50cc scooter using reputable parts that work well together. The following list applies to two-stroke 50cc scooters fitted with a Minarelli horizontal liquid cooled engine:
MINARELLI HORIZONTAL LIQUID COOLED ENGINES
Exhaust systems: Again the
Leo Vince TT is the best budget all round performer. The
Tecnigas Trek or
Artek K1 will see better power gains and release more of the 70cc kits potential. For anyone using a high revving aluminium road going cylinder then the
Yasuni C16 is a must for anyone serious about speed.
Variators: This is the most substantial upgrade for any Minarelli engine as the standard article is very poor. The
Polini 6 or
Polini 9 roller variator kits are very easy to set up and give very consistent performance. Also the
Doppler S2BR works really well on the Minarelli engine as it raises the rollers to
19x15.5 rather than the standard
15x12's.
So far we've mentioned the three main upgrades necessary to up the power of your ped. A carb upgrade and gear kit will further boost performance for anyone who has a larger budget available:
Carburettors: Minarelli engines normally have around an 11.5mm standard carburettor. For everyday use on the road we recommend a 17.5mm carb as it’s still fairly compact so therefore fits into the cramped space it sits. The
Polini 17.5mm carburettor is made by Dell'Orto and can be easily set up for the original air box or a sports foam filter.
Gear Kits: Gear kits increase the gear ratios resulting in an increase in top speed.
Top Racing 4 part kits come pre-pressed for easy fitting.
Polini gear kits have undergone extensive testing to give you the best ratio for use with 70cc cylinder kits.
